Hi, I've been enamoured with Macs for a long time now, and even though I've never owned one before there's a good chance my next computer will be a MacBook. My problem is, it's not me on the lookout for a new laptop right now, but my girlfriend--and she wants something extra-portable, no question. Unfortunately, this is the one virtue that the new Intel generation of MacBooks just doesn't have--we've both checked them out in person and it's just much heavier than what we're looking for. So, does anyone know of any rumors of a smaller MacBook model being planned that we should hold out for? Or should we just accept that we can't have the best of both worlds, and get a refurbished 12" PowerBook G4?
